w. c. McCOY JET FOR GARDEN HOSE Filed Aug. 31, 1957 INVENTOR' Mllimm amw W 1 I ATTORNEYS Patented Jan. 31, 1939 UNITED STATES PATENT @FMQE 7 Claims.

This invention relates to sprinkler units for insertion in the side wall of a hose at spaced intervals.

An object of the present invention is to provide a simple sprinkler unit which may be inserted or built into the hose and clamped or vulcanized into the side wall thereof without such extension beyond the surface of the hose as would materially interfere with winding the hose on a reel.

Another object of this invention is to provide a simple spray adjustment formed in the sprinkler head to control the quantity of water flowing through the nozzzle jets.

Another object of this invention is to provide a sprinkler device which may be inserted through and will be self-retaining in an aperture formed in the side wall of the hose to provide a series of spaced sprinkler heads along the length of the hose.

Other objects and advantages of the construction will be found in the following detailed description and illustrated by the accompanying drawing, in which,

Figure l is a view, in perspective, of a portion of hose, showing the sprinkler unit in place in the hose;

Fig. 2 is a plan view of a section of the hose containing a sprinkler head;

Fig. 3 is a cross sectional view of the hose and sprinkler unit taken substantially on line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary sectional view of the main body of the sprinkler head, showing the jets and bore thereof, taken substantially on the line 44 of Fig. 3.

Referring to the drawingv by numerals of reference, a base portion I of a sprinkler unit is positioned in the water-carrying passage of a hose 2. In the drawing the hose shown is of a type contemplated in the copending application of Herman T. Kraft Serial No. 133,801, filed March 30, 1937. Extending longitudinally from the base of the sprinkler unit is a threaded body portion 3 surrounding a central aperture or bore 4. The bore 4 is flared at its inner end and at its upper end divides into a pair of diametrically opposed nozzles or jets 5. The jets 5 preferably are formed by a jig (not shown) so as to flare the inlet end of the jet but provide a round mouth of smaller cross sectional size. At the uppermost part of the body portion 3 of the sprinkler head is an aperture, axially aligned in respect to the bore 4, and threaded to receive an adjusting screw 6. The lower end of the adjusting screw 6 is conical in shape and serves as a valve 'l to control the amount of water flowing through the jets 5. The conical face of the valve '5 may also seat against a conical valve seat formed at the outlet of the bore 4 to close the bore and prevent the passage of ?1 water through the jets 5.

The exterior of the body portion of the sprinkler is threaded to receive a clamping nut 8. Protruding from the lower surface of the nut 8 is a circumferential ridge 9. There is also a corresponding ridge lti on the base I of the sprinkler head. When the clamping nut 8 is tightened, the two ridges 9 and it are drawn toward each other to press the rubber of the hose wall between them and the body 3 to form an effective seal against leakage of water around the sprinkler unit.

The direction of the jets may be adjusted to different positions circumferentially of the axis of the sprinkler unit, by loosening the clamping nut 8 and turning. the body portion 3 of the sprinkler unit so that the jets are directed to any desired location.

When the hose is attached, the Water pressure from the main forces water along the hose 2 and into the flared end of the bore 4. It passes upwardly through the bore and strikes the valve 1 of the adjusting screw 6. If the valve 1 is not in engagement with the end of the bore 4 the water flows through the jets, out of the sprinkler head. When the valve 1 is in engagement with the seat formed at the outlet end of the bore 4, the sprinkler head is closed. With the aperture for the adjusting screw 6 formed in the body 3 of the sprinkler unit, the quantity of flow can always be efficiently controlled by turning the adjusting screw 6.

Although this device is shown in connection with a flat hose, it is not limited to this type of hose. A modified form of sprinkler head embodying the present invention may be easily made for use in a conventional round type of hose. It is to be understood, also, that various other modifications may be made without departing from the spirit of this invention.

What I claim is:

1. A sprinkler unit comprising a body portion, a radially extending base portion designed to be inserted through an opening in a side wall portion of a flexible hose, means for clamping said body portion to the hose wall, an axial bore through said body portion terminating in opposed upwardly inclined jet openings, and means for controlling the flow through said jet openings.

2. A sprinkler unit comprising a body portion, a radially extending base portionv designed to be inserted through an opening in a side wall portion of a flexible hose, means for clamping said body portion to the hose wall, an axial bore through said body portion terminating in opposed upwardly inclined jet openings, and means for arresting the flow through said jet openings.

3. A sprinkler unit comprising a body portion, a radially extending base portion designed to be inserted through an opening in a side wall portion of a flexible hose, means for clamping said body portion to the hose wall, an axial bore through said body portion terminating in a plurality of radially directed jets, and a conical valve designed to seat and close off the flow through said jets.

4. A sprinkler unit comprising a body portion, a radially extending base portion designed to be inserted through an opening in a side wall portion of a flexible hose, means for clamping said body portion to the hose wall, an axial bore through said body portion terminating in a plurality of radially and upwardly directed jets, and a conical valve to control the flow through said jets.

5. A sprinkler unit comprising a body portion, a flared base portion, an axial bore through said body portion branching into a plurality of angularly directed jets extending through said body portion, the jets being of decreasing cross sectional area from said bore to the openings of the jets, and means for controlling the flow of liquid through said jets.

6. A sprinkler unit comprising a body portion, an axial bore therethrough having a valve seat positioned inwardly from the outer end of the bore, openings through said body portion to said bore disposed outwardly of said valve seat to provide a plurality of angularly directed jets opening from said bore, and a valve adjustably mounted in the portion of said bore above the jets, said valve being adjustable relative to said valve seat for controlling the flow through said jets.

'7. A sprinkler unit comprising a body portion, a radially extending base portion designed to be inserted through an opening in a side wall portion of a flexible hose, means for clamping said body portion to the hose wall, an axial bore through said body portion branching outwardly into a plurality of radially directed jets, and movable means to control and arrest flow through said jets.
